    Abstract: An optical sensor device, includes an optical sensor that has a set of sensor elements, an optical filter that includes a plurality of regions, and one or more processors. A region, of the plurality of regions, includes a first set of optical channels comprising optical channels that are configured to pass light associated with respective subranges of a first wavelength range, a second set of optical channels comprising optical channels that are configured to pass light associated with respective subranges of a second wavelength range, and a third set of optical channels comprising optical channels that are configured to pass light associated with respective subranges of a third wavelength range. The one or more processors are configured to obtain, from the optical sensor, sensor data associated with a scene and determine image information associated with the scene based on the spectral information.

    Abstract: Embodiments of the invention relate to a method for producing a color sensor with a sensor characteristic adjusted by three sensor elements that each comprise an element characteristic, and a color filter cooperating with the sensor elements and consisting of color filter elements that each comprise a filter element characteristic, and to a color sensor. Embodiments include a method with which a color sensor with a precisely adjustable sensor characteristic can be produced from several photosensitive elements and from simple filter elements is solved in that the particular filter element characteristics are adjusted in such a manner that they have in cooperation with the respective element characteristic an interim characteristic of the sensor which deviates from the sensor characteristic on the whole, wherein the sensor characteristic is generated from the interim characteristic by a transformation algorithm using transformation parameters.
